JACKS 


FOR    ALL    KINDS    OF    LIFTING. 


Our  Prices  are  Right. 

^\^E  make  the  most  complete  line,  and  our  Jacks  are  bet- 
ter adapted  to  all  branches  of  railway  service,  from  track 
to  shops,  and  for  carrying  on  locomotives  and  tool  cars, 
than  any  manufactured  in  the  United  States. 

Jacks  for  special  work,  made  to  order  at  short  notice,  and  at 
reasonable  prices.  All  the  Jacks  we  illustrate  are  made  in 
our  own  shops  and  are  fully  guaranteed. 

Have  you  ever  figured  the  cost  of  maintenance  and  repairs 
on  Hydraulic  Jacks  and  loss  of  their  use  while  in  the  hospi- 
tal ?     If  not,  the  figures  will  astonish  you. 

This  trouble  and  expense  can  be  avoided  by  using  the 
Norton  Ball-bearing  Ratchet  Screw  Jacks. 

V/e  make  one  claim  only  —  The  Norton  Jacks  are  the 
best  in  the  world.

The  Norton  Ball=bearing  Ratchet 
Screw  Jacks. 


TpHE  Norton  Ball-bearing  Ratchet  Screw  Jacks  are  constructed 
on  an  entirely  different  principle  from  any  other  Jacks  in  the 
world  ;  as  will  be  seen  by  the  cuts,  they  have  a  stationary  standard 
and  sliding  sleeve  fitting  over  the  same.  The  standard  has  a  re- 
movable nut  (usually  Phosphor  Bronze)  fitted  within  it  and  rest- 
ing on  a  shoulder,  in  which  the  screw  turns  (the  standards  are 
hollow,  and  can  be ////<?^/ with  oil,  thus  keeping  the  screw  constantly 
lubricated).  To  the  upper  end  of  the  screw  is  fastened  a  steel 
gear ;  a  hardened  tool  steel  plate  encircles  the  hub,  and  rests  on 
the  body  of  said  gear,  on  which  are  placed  circular  trains  of 
hardened  steel  balls,  held  in  place  by  rings  between  the  rows  (as 
shown  in  cut).  \\\  the  top,  or  head  of  the  sliding  sleeve  (which  is 
bored  to  fit  standard),  is  placed  another  hardened  tool  steel  plate 
with  a  hole  in  the  centre,  through  which  the  end  of  the  screw 
projects. 

When  the  Jack  is  assembled  the  sleeve  slides  down  over  the 
screw  and  standard,  the  bearing  ])late  in  the  head  resting  on  the 
balls  on  the  plate  on  the  gear,  so  that  the  whole  weight  is  carried 
by  the  balls  (between  the  steel  plates),  which  act  as  a  thrust-bear- 
ing between  the  screw  and  head  of  the  sleeve,  reducing  the  friction 
and  increasing  the  lifting  power  of  the  Jack. 

The  sleeve  which  revolves  on  the  standard,  allowing  the  lever  to 
be  used  from  either  side,  carries  the  load,  and  is  raised  or  lowered 
by  the  screw,  which  is  turned  by  means  of  a  gear  on  the  rachet 
shaft,  engaging  with  the  gear  on  the  screw,  and  operated  by  a  re- 
versible ratchet  and  lever  having  the  ///  and  do7vn,  or  ''pump 
handle""  motion.  This  is  the  only  screw  Jack  made  having  this 
motion  of  the  lever.  The  sleeve  at  the  lower  end  is  provided 
with  a  '' stop  dog''  or  pawl,  which  prevents  the  screw  from  being 
run  out  of  the  nut. 

The  advantage  of  this  sliding  sleeve  cannot  be  over  estimated. 
It  takes  all  the  side  strain  off  the  screw,  preventing  it  from  bending, 
and  also  protecting  all  the  working  parts  from  sand,  coal-dirt  and 
water,  making  it  the  only  Jae-k  suitable  to  carry  on  locomotives. 

All  of  the  Norton  Railroad  Jacks  are  steel  and  malleable  iron 
throughout. 


A.  O.  Norton,  Boston.  Mass.,  U.  S.  A.,  and  Coaticook,  P.O.,  Canada. 

WHY  WE  CLAIM  THE  NORTON  JACKS 

ARE  SUPERIOR  TO  ALL  OTHERS, 

Especially  for   Railway  Service. 

Because   of  their  Simplicity,  Durability  and   Cheapness 

They  are  the  Lightest  Ratchet  Jacks  in  the  world  ot  same 
capacity. 

Cost  Less  for  maintenance,  are  always  Safe  and  Reliable, 

even  in  the  hands  of  careless  and  unskilled  workmen,  as  the  screvv 
holds  the  load  without  blocking,  and  cannot  drop  or  run  down. 
This  is  a  very  important  feature  in  a  Railway  Jack  and  should 
not  be  overlooked. 

The  screws  are  Self-lubricating.  Ball-bearings  never  wear, 
and  seldom  need  oiling  or  attention. 

They  can  be  operated  by  ordinary  workmen  without  previous 
instructions. 

'I'hey  can  be  left  standing  in  Tool  Car  or  Shop,  or  carried  on 
Locomotive  for  Months  at  a  time  without  any  attention 
whatever,  and  be  found  Ready  for  Service  when  needed,  as 
there  is  no  Alcohol,  Packing  or  Valves  to  keep  in  order. 

All  Parts  are  Interchangeable,  and  can  be  replaced  ina  few 
minutes  by  ordinary  workmen  at  trifling  cost  without  returning  to 
Factory. 

The  Norton  Journal  Jacks  Weigh  about  one-third  and 
Cost  about  one-fourth  as  much  as  Hydraulics  of  same 
capacity,  for  same  purpose. 

All  of  our  Screw  Jacks  can  be  used  in  any  position,  flat  for 
pushing  or  bottom  up,  if  necessary. 

The  cost  for  maintenance  and  repairs  on  all  Jacks  in  use  for 
past  four  years  averages  less  than  1  per  cent,  per  annum. 

We  will  guarantee  to  keep  our  Jacks  in  perfect  working  order 
for  five  years  for  one-half  what  it  costs  for  Alcohol  alone,  for 
Hydraulics  of  same  capacity  and  service.

material,   and    have   given    excellent   satisfaction. 

When  raising  light  load  (30  to  50  tons)  use  ratchet  on 
upper  shaft,   which   gives  more  speed. 

When  full  power  of  Jack  is  required,  use  ratchet  on 
lower  shaft.

Thest  Jacks  are  intended  for  car  work,  where  lon^;  lift  is  needed,  and 
can  be  used  with  crank  on  empty  cars,  or  light  load,  wiiich  is  much  quicker 
than  pumping  up  with  lever.  Another  saving  of  time  is,  the  car  can  be  raised 
and  left  Standing  on  the  Jacks  without  blocking,  while  trucks  are 
changed.

NON=BALL=BEARINQ  JACKS. 


This  Cut  shows  construction  of  the  Norton  Jack 
without  BalhBearings. 

Our  Non-lJalMJearing  Jacks  are  made  on  the  same  princii)le 
as  the  Bali-Bearings,  except  the  load  is  raised  by  the  end  of  the 
screw,  which  rests  on  a  hardened  steel  step,  or  bushing,  in  the 
head  of  the  sliding  sleeve.  Up  to  15  tons  they  are  as  good  as  the 
Bali-Bearing,  except  they  need  a  little  more' attention  in  oiling. 
All  are  fully  guaranteed. 

DIRECTIONS  FOR  NORTON  JACK  WITHOUT 
BALL=BEARINQ. 

Keep  working  parts  xue/l  oiled.  Take  particular  pains  with  tlie  top  hole,  as 
all  of  the  loeight  is  l)i)rne  on  the  ,?;;f/ of  the  screw.  In  oiling  the  top  hole,  first 
till  the  hole  with  oil.  Then  raisi  the  shell  a  little  to  allow  the  oil  to  settle  well 
on  end  of  Screw.  Do  not  neglect  this,  and  use  plenty  of  oil.  Also  see  that  the 
screw  is  kept  well  oiled.  Keep  gears  7vell  in  mesh.  '  To  adjtist gears— \.oo%en 
four  nuts  on  cap-holts  and  check  nut  on  set  screw  at  bottom  of  cap.  Turn  set 
screw  till  gears  are  as  close  in  meshes  as  they  will  run  freely.  Then  tighten 
check  nut  on  set  screw  to  hold  gears  in  place,  and  tighten  the  nuts  on  cap-bolts. 
To  take  Jack  apart,  take  the  nuts  off  liolding  cap,  remove  the  ratchet  and  gear, 
then  lift  the  shell  up,  pressing  bottom  dog  to  let  it  pass  groove  in  top  of  standard.

This  Jack  is  intended  for  carrying  on  locomotives,  for  putting  in  brasses, 
and  yard  work. 

It  can  be  placed  almost  instantly  and  works  very  rapidly.  The  screw  being 
protected,  it  never  gets  rusty  and  useless  from  exposure  on  the  engine,  as  is  so 
often  the  case  with  common  Bottle  Jacks,  but  is  always  ready  for  USe. 

Brasses  can  be  changed  in  half  the  time,  and  much  easier,  than  with  the 
old  style  Jack. 

It  would  be  economy  to  supply  every  car  inspector  with  one.

This  Jack  is  made  of  malleable  iron  and  steel  throughout,  with 
phosphor  bronze  nut,  same  as  all  our  bail-bearing  Railway  Jacks. 

Instead  of  ball  bearings,  the  end  of  screw  is  conical  shape, 
working  on  a  removable,  hardened  steel  plate,  fitted  in  the  head 
of  sliding  sleeve.  In  case  of  wear,  this  plate  can  be  replaced  at 
slight  expense. 

Where  a  very  serviceable  and  low-priced  Jack,  from  lo^o  ij

guaranteed.

These  Jacks  are  made  on  the  same  principle  as  the  Railway 
Jacks,  and  are  unsurpassed  for  all  kinds  of  work. 

They  are  especially  adapted  in  price  and  quality  to  the  wants

ordinary  work,  and  in  all  respects  suitable  for  general  service. 

For  raising  buildings  where  the  sills  are  close  to  the  ground, 
the  hook  will  save  all  the  t/iX^i.'-ifijr,  conse([uently  the  Jacks  can 
be  placed  and  the  building  raised  with  much  less  labor  and  ex-

THE   NORTON   "SURE   DROP" 
TRACK  JACK. 


DESCRIPTION. 

The  body  of  the  Jack  is  of  malleable  iron,  made  in  two  pieces, 
the  sides  and  bearings  of  each  part  being  accurately  milled,  joined 
together  and  firmly  riveted  above  the  foot,  which  is  in  one  piece,  mak- 
ing a  strong,  solid  base.  The  lifting  bar  is  made  from  best 
quality  forged  steel,  milled  to  fit  body  of  Jack,  with  teeth 
cut  on  two  sides,  one  for  lifting  and  one  for  holding  pawl. 
The  teeth  in  lifting  side  of  bar  are  cut  square  on  top,  making  it 
impossible  for  pawl  to  become  disengaged  while  lifting. 

The  mechanism  for  lifting  consists  of  a  cam  on  end  of  lever 
socket  3  (see  cut  3),  working  in  strap  which  carries  lifting  pawl  (!. 
Strap  and  cam  are  bored  and  turned  to  fit,  and  hardened. 
The  cam  turns  on  a  f  inch  hardened  tool  steel  pin,  which  is 
keyed  to  frame  so  it  cannot  turn.  The  cam  has  sufificient 
throw  to  raise  the  bar  \  inch,  1  inch,  or  U  inches,  as  may  be  de- 
sired, with  one  stroke  of  the  lever. 

The  teeth  on  holding  side  of  bar  are  cut  in  line  with  an 
arc  of  a  circle  struck  from  centre  of  pin  in  holding  pawl  4  (see 
cut).     Hinged  to  holding  pawl  4,  is  tripping  cam  T). 

To  raise,  turn  tripping  cam  to  left  (see  fig.  1). 
To  trip  the  jack  it  is  only  necessary  to  turn  tripping  cam 
into  position  as  shown  in  cut  2,  raise  the  lever  and  turn 
lifting  pawl  back.  Pressing  down  on  the  lever  brings  the 
end  of  lever  socket  in  contact  with  tripping  cam  5,  forming 
a  wedge,  which  in  combination  with  the  shape  of  the  teeth  on 
lifting  bar,  before  mentioned,  is  so  powerful  that  a  man  can 
easily  and  instantly  trip  with  one  hand,  any  load  that  can 
be  raised  with  the  Jack,  even  with  two  or  three  men  on 
the  lever.

CLAinS. 

We  claim  that  the  "  Norton  "  is  the  most  perfectly  made 
track  Jack  in  the  market.  Our  lifting  device  is  the  easiest, 
quickest  working  and  most  powerful  ever  applied  to 
any  track  Jack.     Our  tripping  device    is    perfect.     It  is 

not  necessary  to  lift  the  load  before  it  can  be  dropped,  as 
with  other  Jacks.  There  are  less  parts  to  wear  and  keep 
in  repair,  and  each  part  can  be  duplicated. 

The  wear,  if  any,  being  on  the  cam  (which  is  protected  from 
the  sand  and  grit  by  the  strap)  is  distributed  over  so  much  surface, 
that  it  cannot  interfere  with  the  working  of  the  Jack, 
while  the  perfect  fitting  of  the  parts  is  a  great  improvement 
over  other  Jacks  which  are  nearly  all  made  from  castings  put  to- 
gether in  the  rough,  with  the  lifting  pawls  hinged  on  small  pins. 

In  a  word,  we  claim  the  "Norton"  Jacr.s  are  the  nearest 
perfection  of  any  tools  of  the  kind  ever  produced.
